What else can I help you with?
What tiny cubes contain smooth muscle that can contract and relax thereby affecting the flow of air into the alveoli?
You do not have any such cubes in your respiratory system.
Can you see sarcomeres in smooth muscle?
No, sarcomeres are not visible in smooth muscle. Smooth muscle lacks the organized sarcomere structure found in striated muscle, such as skeletal and cardiac muscle. Instead, smooth muscle has a more scattered arrangement of contractile proteins.
Does the trachea have skeletal muscle?
No, the trachea does not have skeletal muscle. Instead, it is composed of smooth muscle, cartilage, and connective tissue. Smooth muscle allows for involuntary control of the trachea's diameter and airflow.
How does the contraction mechanism of smooth muscle compare to that of skeletal muscle and cardiac muscle?
Smooth muscle, skeletal muscle, and cardiac muscle all contract in response to signals from the nervous system or hormones. However, the contraction mechanism of smooth muscle is different from that of skeletal and cardiac muscle. Smooth muscle contracts more slowly and can sustain contractions for longer periods of time compared to skeletal and cardiac muscle. Additionally, smooth muscle does not have striations like skeletal and cardiac muscle, which gives it a more uniform appearance.
What are the key differences in the structure and function between smooth muscle and cardiac muscle?
Smooth muscle is found in the walls of internal organs and blood vessels, while cardiac muscle is found in the heart. Smooth muscle is involuntary and under autonomic control, while cardiac muscle is also involuntary but has its own specialized conduction system. Smooth muscle cells are spindle-shaped and have a single nucleus, while cardiac muscle cells are branched and have one or two nuclei. Smooth muscle contracts slowly and rhythmically, while cardiac muscle contracts quickly and continuously.
What tiny cubes contain smooth muscle that can contract and relax thereby affecting the flow of air into the alveoli?
You do not have any such cubes in your respiratory system.
What small structures located within the bronchial tree are composed primarily of smooth muscle?
Bronchioles are smaller tube divisions of bronchi. Walls of bronchioles contain smooth muscle and no cartilage. This helps in contraction and relaxation which allows the flow of air to alveoli.
What is the muscle that is found in the small intestine?
smooth musclesmooth muscle
Is an ulcer a cardiac muscle or a smooth muscle?
Smooth muscle
Alveoli have neither smooth muscle or mucous secreting cells?
That is correct. Alveoli only contain only two types of cells: Type I cells that are like thin sheets and make up the actually wall of the alveoli, and Type II cells that secrete a substance called surfactant that helps to hold the alveoli open. There can also be some macrophages present in the alveoli to destroy invading bacteria.
Which muscle tissue is involuntary and not striated?
SmoothI'm POSITIVE it's the Skeletal Muscle!
Is voluntary muscle smooth muscle?
yes it is.....
Is muscle cell is smooth when hungry?
No, "smooth" muscle is a type of muscle.
Do smooth muscle cells posses central nuclei but lack striations?
Smooth muscle is not striated, hence the name smooth muscle.nonotcardiac muscle
Detrusor muscle what are the 3 layers?
Outer = longitudinal smooth muscle Middle= circular smooth muscle Innermost= longitudinal smooth muscle
What type of muscle is found in the wall of the stomach?
smooth muscle tissue. it is an involuntary muscle and the stomach can be controled by you.
What are the 3 subtypes of muscle tissue?
Striated,smooth,and skelital cardiac, skeletal, and smooth
